Question description

Architecture and Design

The
objective of this assignment is to apply and consolidate skills
acquired in the analysis, architecture, and design disciplines through
analysis of a simple case study, and to express the results through the
relevant UML diagrams.

Part A – Non Functional Requirements (20 marks)

1.
Analyse the Case Study documents and determine the non-functional
requirements (NFRs) or system quality attributes necessary to meet the
needs identified in the Case Study. Document your analysis with a System
Wide Requirement document. Make sure your document addresses:

a) Required system functionality not captured by a single use case (eg auditing, printing, authentication).

b) The FURPS+ categories of system attributes.

c) Any required system interfaces with external systems.

d) Any business rules that must be applied.

e) Any constraints that will affect the design of the system.

Use
the System Wide Requirement Specification template provided in the
Resources/Assignment 2 section of the subject Interact site. (20 marks)

Part B – System Architecture (40 marks)

2.
Analyse the Case Study documents and develop a candidate architecture
to meet the functional and non-functional requirements you have
identified in Assignment 1 and Part A of Assignment 2. Document this
candidate architecture with:

i. An Architectural Notebook. Make sure this notebook addresses:

a) The key concerns driving the overall architecture.

b) Assumptions and dependencies

c) Architecturally significant requirements

d) Decisions, constraints, and justifications that shape the architecture

e) Architectural mechanisms to be applied

f) Key abstractions

g) Any architectural frameworks or patterns that will be applied

Use the Architectural Notebook template provided in the Resources/Assignment 2 section of the subject Interact site. (20 marks)

ii. A high level Logical View of the architecture in the form of a UML component diagram. (10 marks)

iii.
A Physical View of the architecture showing how components will be
deployed on hardware in the form of a UML Deployment Diagram. (10 marks)

Part C – Detailed Design (30 marks)

3.
Show how your architecture will support the critical core use case for
the system by developing a detailed design to support that use case.
Your design should be consistent with your architecture and respect any
component and hardware boundaries. Document your design with:

This
assignment elicits performance of taught skills in the requirement and
analysis areas relevant to the following learning objectives:

be able to analyse and validate system requirements;

be able to produce and validate analysis and design models for a system;

be able to evaluate a problem and determine the appropriate architectural style for the solutio

be able to evaluate and choose appropriate software design patterns to compose the design of a software system

be able to demonstrate use of a CASE tool to document the models in a system
